Which chamber of the heart exits into the pulmonary trunk?

Answers

Answer 1
Answer:

Answer: the right ventricle

Explanation:

The pulmonary trunk originates from the right ventricle through which deoxygenated blood is pumped into the lungs.

The pulmonary trunk divides into right and left pulmonary artery which carries blood to their respective lungs.

Blood flow into the pulmonary trunk is regulated by the semilunar valve.
Answer 2
Answer:

Final answer:

The right ventricle of the heart exits into the pulmonary trunk. This process is part of our body's pulmonary circulation, responsible for oxygenating blood.

Explanation:

The chamber of the heart that exits into the pulmonary trunk is the right ventricle. In the human heart, blood flows from the right atrium into the right ventricle after which it's pumped out of the heart into the pulmonary trunk. This blood then splits between the two pulmonary arteries that carry it to the lungs where it gets oxygenated. This process is part of the pulmonary circulation which is responsible for oxygenating blood. It's crucial for maintaining the body's overall oxygen levels and blood supply.

Answers

The right option is; b.

Wheat and corn are common products of tropical plantations is not true concerning tropical plantations.

Tropical plantations is a type of agriculture in which perennial plants are grown for several years. Tropical plantations are usually practiced in regions with humid, tropical climates and plants such as cocoa, coffee, tea, coconut, rubber and oil palm are the common crops that are cultivated. The crops are mostly exported and they serve as important source of income. Wheat and corn are not common products of tropical plantations .

The ability to navigate, hunt, and communicate by electric current in water most likely helps make up for the effect of dark, murky water on which sense?

Answers

The answer is a vision.

If fish live in a dark, murky water, that means that their sense of vision is affected. In dark, murky water they could not see anything. So, fish that lives in this kind of water developed the ability to o navigate, hunt, and communicate by electric current in water. This ability is known as electroreception. Among fish, electroreception is present in some sharks and rays, and electric eels

1. Cells use glucose to make (1 point)energy.proteins.
enzymes.
vitamins.






2. Which of the following is broken down to provide the body with glucose? (1 point)proteins
vegetable oils and animal fats
simple sugars and starches
vitamins






3. What makes essential fatty acids and essential amino acids different from ones that aren’t essential? (1 point)Essential nutrients are more important than others, so the body needs more of them.
Nutrients that are essential cannot be made by the body, so they must be obtained from food.
Brain cells need only the essential nutrients, so they are important for clear thinking.
All essential nutrients are water-soluble, so they all must be replaced every day.






4. A car is to gasoline as your body is to (1 point)your stomach.
your kidneys.
food.
enzymes.






5. Starches are to simple sugars as proteins are to (1 point)fatty acids.
double bonds.
amino acids.
carbohydrates.

Answers

1.Cells undergo respiration to produce energy by using glucose.
2. simple sugars and starches contain glucose.
3. Essential nutrients cannot be produced by the body.
4. Your body is to your food.
