Question

Two types of blood circulation in the human body.....
​

Answer 1

Answer:

1. Systematic Circulation

2. Pulmonary circulation

Explanation:

The left ventricle pumps oxygen-rich blood into the major artery in the systemic circulation (aorta). Blood flows from the major artery to smaller and smaller arteries before entering the capillary network. The blood picks up carbon dioxide and waste materials while dropping off oxygen, minerals, and other vital substances. The oxygen-depleted blood is collected in veins and sent to the right atrium and right ventricle.

The start of pulmonary circulation is here: Low-oxygen blood is pumped from the right ventricle into the pulmonary artery, which branches into smaller and smaller arteries and capillaries. Around the pulmonary vesicles, capillaries create a fine network (grape-like air sacs at the end of the airways). Inside the pulmonary vesicles, carbon dioxide from the blood is released into the air, and fresh oxygen enters the bloodstream. Carbon dioxide leaves our bodies when we exhale. The pulmonary veins and the left atrium carry oxygen-rich blood to the left ventricle. A new cycle of systemic circulation begins with the next heartbeat.

Answer 2

In the human body, there are two types of blood circulation.

1. Systematic Circulation

• In the systemic circulation, the left ventricle pumps oxygen-rich blood into the major arteries, including aorta.
• Before entering the capillary network, blood flows from the major artery to smaller and smaller arteries.
• The blood absorbs carbon dioxide and waste while excreting oxygen, minerals, and other vital substances.
• The deoxygenated blood is collected in veins and delivered to the right atrium and right ventricle.

2. Pulmonary circulation

• In pulmonary circulation, the right ventricle pumps low-oxygen blood into the pulmonary artery, which branches into smaller and smaller arteries and capillaries.
• Capillaries form a fine network around the pulmonary vesicles (grape-like air sacs at the end of the airways).
• Carbon dioxide from the blood is released into the air by the pulmonary vesicles, and fresh oxygen enters the bloodstream.
• When we exhale, carbon dioxide leaves our bodies.
• The pulmonary veins and left atrium transport oxygenated blood to the left ventricle.
• With the next heartbeat, a new cycle of systematic circulation begins.
