The diagram shows a simplified version of how the blood moves around the body of an animal. Is the blood at point D oxygenated or deoxygenated?

Answers

Answer:

oxygenated

hope u got your answer

In the given diagram, point D is oxygenated blood, as it carries oxygen from heart to cells.

What is heart?

The main organ of your cardiovascular system, a network of blood vessels that pumps blood throughout your body, is your heart.

It also collaborates with other bodily systems to regulate your heart rate and blood pressure. Your family history, personal health history, and lifestyle all have an impact on how well your heart functions.

The heart is located between the two lungs, slightly to the left of center, behind the breastbone in humans. It is supported by the diaphragm, the muscular wall that separates the chest from the abdominal cavity.

It's the muscle at the heart of your circulatory system that pumps blood throughout your body as your heart beats. This blood transports oxygen and nutrients to all parts of your body while removing waste and carbon dioxide.

Here, the red vessels are arteries while blue vessel is vein, arteries always carries oxygenated blood and vein carries deoxygenated blood.

Thus, the point D carries oxygenated blood.

Security: pelvic girdle is more secure, deeper socket. there are more dislocated shoulders than dislocated hips

ability to bear weight: pelvic girdle can bear more weight-the pelvic girdle has bones that are fused (os coxa) and a joint with the sacrum. the pectoral girdle has a little bone called the clavicle connecting it to the body wall.

Explanation:

The pelvic gridle is rigid to protect internal organs and support body weight whereas pectoral gridle require to provide movement to upper limbs.

A group of students discusses what they
believe will be the outcome of an experiment
they are about to conduct. Each student
records a statement that will either be
proven or disproven by the experiment.
Each member of the group carefully watches
as the experiment proceeds. One group

After the experiment is complete, the group
discusses their observations. They review their
notes and create a graph that shows the
results of the experiment. The group
discusses what these findings might mean.
Now that the group has decided on a
hypothesis, they are ready to proceed with
the experiment. As they work, the group is
