Which of the following statements accurately describes how blood flows through the heart? A. Oxygen-rich blood is carried in the right pulmonary veins from the left lung to the right atrium.
B. Oxygen-rich blood is carried in the aorta from the left ventricle to the body.
C. Oxygen-poor blood is carried through the left pulmonary veins to the left atrium.
D. Oxygen-poor blood is carried through the inferior vena cava to the left atrium.

Answers

Answer 1

Answer: B. Oxygen-rich blood is carried in the aorta from the left ventricle to the body.

Superior and inferior vena cava enters the right atrium which is pumped by the tricuspid valve to the right ventricle and to the pulmonary valve to the pulmonary artery then to the lungs from the lungs back thru the pulmonary veins entering the left atrium pumped by the mitral valve to the left ventricle to the aortic valve to the aorta.

The circulatory system is important in meeting the needs of all cells in the body because it offers means of transport by which cells obtain the materials needed to live and function.

What component of muscle is described as a bundle of actin, mysoin, and other protien filaments

Answers

The component of muscle which is described as a bundle of actin, myosin, and other protein filaments is referred to as a tendon.

What is a Tendon?

This structure falls under the category of connective tissues and is involved in the attachment of the muscles to the bones as they work together in ensuring adequate movement of body part is achieved.

They made up of different types of proteins such as actin, myosin, and other types of protein filaments and are very flexible which helps them absorb pressure.

This is therefore the reason why tendon was chosen as the most appropriate choice.

Explain how the human body cools itself.

Answers

Hi there!

There is a way that the human body cools itself, but it sounds so weird!

Did you know that when you sweat after doing something constantly, the sweat tries to cool the body down? It's true!

I learned this is physical science class, and we tested it for ourselves. We ran around a bunch of times around my old school and then we started sweating. Not too long afterwards, we started cooling down because of the sweat.

Weird, right?

Hope this helps!

Message me if you need anything else! :D

Whenever we sweat our body empty's salt out and we can cool of by simply our sweat drying. :)

it can be scientifically proven if you need reasons.

i really hope that this helps you a lot
