Your circulatory system is made up of several parts, including your:
Heart. This muscular organ works to pump blood throughout your body via an intricate network of blood vessels.
Arteries. These thick-walled blood vessels carry oxygenated blood away from your heart.
Veins. These blood vessels carry deoxygenated blood back toward your heart.
Capillaries. These tiny blood vessels facilitate the exchange of oxygen, nutrients, and waste between your circulatory system and your organs and tissues.
Interesting facts about the circulatory system
Your heart pumps about 5 liters of blood per minuteTrusted Source, but it’s only about the size of your fistTrusted Source.
It’s estimated that in a 70-year period, your heart will beat over 2.5 billion timesTrusted Source.
In most adult humans, a normal resting heart rate is between 60 to 100 beats per minuteTrusted Source.
The total length of all of the blood vessels in your body is about 60,000 miles.
Capillaries are your most numerous blood vessels and also the smallest. Red blood cells often have to move through the capillaries in single-file.
Your blood pressure changes throughout the day. It’s lowest when you’re asleep, and it peaks in the middle of the afternoon.
How does it work?
Your circulatory system is vital to your survival. Its function is to distribute blood and other nutrients to all your body’s organs and tissues.
The small blood vessels called capillaries facilitate the exchange of oxygen and nutrients between your blood and the cells in your body. Carbon dioxide and other waste products, which are expelled from your body, are also exchanged via your capillaries. These tiny capillaries are spread throughout your body so that they can reach every cell.
Let’s follow the blood on a simple loop through the circulatory system to see how it works:
Oxygen-depleted blood returns to your heart (the right side) via the veins.
Your heart pumps this blood to the lungs. In the lungs, the blood gets rid of carbon dioxide and picks up fresh oxygen.
Newly oxygenated blood returns to the other side of the heart (the left side), where it’s then pumped into the arteries.
Eventually, the blood enters the capillaries. Here, it releases oxygen and nutrients to your body’s organs and tissues. It then picks up carbon dioxide and other waste products.
The oxygen-depleted blood returns to the heart through the veins, and the cycle begins all over again.
The circulatory system can also respond to various stimuli to regulate the flow of blood. Examples of these stimuli include changes in:
blood volume
hormones
electrolytes
Circulatory system conditions
Below, we’ll explore some of the most common conditions that can affect the health of your circulatory system.
Atherosclerosis
Atherosclerosis is when plaque builds up along the walls of your arteries. Risk factors that can contribute to plaque buildup include:
high blood pressure
high cholesterol
tobacco use
diabetes
an unhealthy diet
low levels of physical activity
being overweight or obese
Atherosclerosis can gradually make the arteries narrower, affecting the amount of blood that can flow through them. Because of this, organs and tissues may not get enough oxygen.
When atherosclerosis affects the arteries of your heart, it’s called coronary artery disease. Other arteries in your body can also be affected as well. This is called peripheral artery disease, which affects how well blood can flow to your legs, feet, arms, and hands.
In some cases, an artery may become completely blocked by plaque or a blood clot. When this happens, a heart attack or stroke can occur.
High blood pressure
Your blood pressure is the force that your blood exerts on the walls of your arteries as your heart pumps. High blood pressure can eventually damage your heart and blood vessels, as well as other organs like your brain, kidneys, and eyes.
Angina
Angina is chest pain that occurs when your heart isn’t getting enough oxygen. It’s often caused by coronary artery disease, which makes the arteries supplying the heart narrower due to plaque buildup.
Arrhythmia
An arrhythmia is an abnormal heart rhythm. When you have an arrhythmia, your heart may be beating too fast (tachycardia), too slowly (bradycardia), or irregularly. It happens due to changes in the heart or its electrical signals.
Varicose veins
Your veins contain valves that help keep oxygen-depleted blood flowing toward your heart. When these valves fail, blood collects in the veins, which can cause them to bulge and become swollen or painful.
Varicose veins most often appear on the lower legs.
Function is a transport blood and nutrients to parts of the body
Blood flow control by heart , veins and areteries

Answers
Answer:
Explanation:
fractured bone as the arm is swollen
Bruising can happen with almost any kind of tissue damage, including blood leaking from a broken bone. 1 The bigger the area of bruising, the more likely the damage is deep—possibly bone deep. Broken bones often swell. Swelling can be a sign that it's broken.
it will affect your skeletal system as you are unable to moth that part of your body and it also affect your muscular system as you can move your arm.
Broken bones are one of the most common orthopedic injuries. Fractures require treatment which may be as simple as rest, or as invasive as surgery. There are many factors that must be considered to determine the most appropriate treatment of a broken bone including: Some of the most frequently used fracture treatments are described here
that is most likely nerve damage as there is no bruising and it is numb so here nerve damage will be most logical.
muscular and nervous system as you are unable to feel or move your muscle.
muscle strain as it is when she overexercise her muscle which I sometimes experience at night.
it will most likely affect your muscular system
For immediate self-care of a sprain, try the R.I.C.E. approach — rest, ice, compression, elevation: Rest. Avoid activities that cause pain, swelling or discomfort. But don't avoid all physical activity.
skeletal and muscular, the muscle is swollen and affected by the break in the skeletal system.
A treatment would be icing the forearm, and applying a cast.
Patient 2 has nerve damage
The nervous system is affected by the damage.
A treatment would be managing blood sugar levels because the patient has type 2 diabetes. Nerve pain medication would block pain by the damaged nerves.
Patient C has a muscle sprain because when she ran, she might have stepped incorrectly, straining the muscle.
The muscular system is affected by this.
Cold compressions, keeping the calf elevated and rest.

1) What determines which
genes will be an advantage
and which ones will be a
disadvantage?
2) How does this experiment
illustrate Darwin's theory of
Natural Selection?
Answers
Answer:
1. While you do inherit certain genes from your mother and father, you will get separate versions of those genes meaning there will be advantages and disadvantages.
2. Charles Darwin, Natural selection explains how the genetic traits of a species may change over time. This may lead to speciation and the formation of a distinct new species.
Explanation:
1. Something that is an advantage towards the person achieving the genes is whether or not that trait is beneficial. For example, your body size can be determined by your mother or father which can lead to negative health or positive health. That can be a disadvantage (shape, being born with asthma, inheriting a mental illness). All can be achieved because of a parent.
2. Charles Darwin and his theory illustrate genes because as a parent hands over a gene during pregnancy it can be altered because it is a different version of that gene and that can lead to different species whether it is visible or not.

Write down a paragraph (7-8 lines) to say " No to single-use plastics"
Don't copy from Goo gle
Answers
Answer:
Single use plastic is one of the most prevalent causes of pollution including environmental as well as water pollution. It has devastating impact on oceans, sea animals and hydrophytes. Therefore ban on single use plastic is very important.
Explanation:
we Plastic packaging serves several important functions in our modern lives, which are the primary reasons we rely on it: Protection: protects vulnerable products from damage whilst in transit and from contamination or damage by moisture, humidity, gases, microorganisms, insects and light.
Plastic bags have become a threat to the life of animals living on earth as well as in water. Chemicals released by waste plastic bags enter the soil and make it infertile. Plastic bags are having a negative impact on human health. Plastic bags lead to the drainage problem.
Pls give brainliest!
Single-use plastics are a glaring example of the problems with throwaway culture. Instead of investing in quality goods that will last, we often prioritize convenience over durability and consideration of long-term impacts. Our reliance on these plastics means we are accumulating waste at a staggering rate. We produce 300 million tons of plastic each year worldwide, half of which is for single-use items. That’s nearly equivalent to the weight of the entire human population.
Reducing plastic use is the most effective means of avoiding this waste (and the impacts linked to plastic production and use). Carrying reusable bags and bottles is one great way to avoid single-use plastics in our day-to-day lives; more on preventing plastic waste can be found below.
Recycling more plastic, more frequently, reduces its footprint. Polyethylene terephthalate, one of the most commonly recycled plastics and the material that makes up most water and soda bottles, can be turned into everything from polyester fabric to automotive parts. But a whopping 91 percent of all plastic isn’t recycled at all. Instead it ends up in landfills or in the environment. Single-use plastics in particular—especially small items like straws, bags, and cutlery—are traditionally hard to recycle because they fall into the crevices of recycling machinery and therefore are often not accepted by recycling centers.
Left alone, plastics don’t really break down; they just break up. Over time, sun and heat slowly turn plastics into smaller and smaller pieces until they eventually become what are known as microplastics. These microscopic plastic fragments, no more than 5 millimeters long, are hard to detect—and are just about everywhere. Some microplastics are even small by design, like the microbeads used in facial scrubs or the microfibers in polyester clothing. They end up in the water, eaten by wildlife, and inside our bodies. They’ve even made their way up to the secluded Pyrenees mountain range and down to the bottom of the Mariana Trench. For wildlife, microplastics can be particularly dangerous; when eaten they can easily accumulate inside an animal’s body and cause health issues, like punctured organs or fatal intestinal blockages.
Exposure to microplastics, as well as the chemicals that are added to plastics during processing, harm our health. Many of the chemicals in plastics are known endocrine disruptors,and research has suggested that human exposure could cause health impacts including hormonal imbalances, reproductive problems like infertility, and even cancer. The phthalate DEHP, as just one example from dozens, is often added to plastic goods like shower curtains and garden hoses to make them more flexible—but was also found to be a probable human carcinogen by the U.S. Environmental Protection Agency.
