Where does blood become oxygenated?

Which side of the heart contains oxygenated blood?

What kind of muscle is found in the heart?

Answer 1

Answer:

1. large organisms need transport system to provide the nutrition to the cells of the body
2. double circulatory system means that the blood passes through the heart twice 1st time taking oxygenated blood from heart and 2nd time taking de-oxygenated blood towards heart
3. the blood rich in oxygen is called oxygenated blood ,In this oxygen concentration is more
4. blood become oxygenated in lungs
5. left chambers of heart receive oxygenated blood
6. kind of muscle is found in the heart are Cardiac muscles

1- Why do large organisms need transport systems?

Ans- Mutlicellular oragnism need a transportation system for oxygen and water bescause there body is complex and transport oxygen and other minerals cannot be done by osmosis or transport of oxygen by high pressure to low pressure.

Therefore , there is a need of transport system of oxygen and other mineral in multicellular organism.

2- What is a double circulatory system?

Ans- The human circulatory system is a double circulatory system. It has two separate circuits and blood passes through the heart twice: the pulmonary circuit is between the heart and lungs. the systemic circuit is between the heart and the other organs.

3- What is oxygenated blood?

Ans- Oxygenated blood is also called arterial blood as the arteries deliver oxygenated blood to different parts of the body through the pulmonary veins.

Blood is the only fluid connective tissue in the human body and is mainly involved in transporting water, gas, food, minerals and other essential molecules for the proper functioning of the cells, tissues and other organs of our body.

Oxygenated blood can be simply defined as a blood cell with large percentage of oxygen and low in carbon dioxide. It appears bright red in colour and travels away from the heart to different parts of the body.

4- Where does blood become oxygenated?

Ans- The heart consists of four chambers in which blood flows. Blood enters the right atrium and passes through the right ventricle. The right ventricle pumps the blood to the lungs where it becomes oxygenated. The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium.

5- Which side of the heart contains oxygenated blood?

Ans- Blood enters the right atrium and passes through the right ventricle. The right ventricle pumps the blood to the lungs where it becomes oxygenated. The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium. From the left atrium blood flows into the left ventricle .

6- What kind of muscle is found in the heart?

Ans- Cardiac muscle cells are located in the walls of the heart, appear striated, and are under involuntary control. Smooth muscle fibers are located in walls of hollow visceral organs, except the heart, appear spindle-shaped, and are also under involuntary control.
