E) II and III

Answer 1

A blood cell with a high percentage of oxygen and a low percentage of carbon dioxide is known as oxygenated blood. It has a bright red appearance and moves from the heart to various parts of the body.

Complete answer:
The human circulatory system is a dual system, which means there are two distinct blood flow systems: pulmonary circulation and systemic circulation. The adult human heart is divided into two pumps: the right atrium and ventricle, which pump deoxygenated blood into the pulmonary circulation, and the left atrium and ventricle, which pump oxygenated blood into the systemic circulation.

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

Blood is the human body's only fluid connective tissue, and it is primarily responsible for carrying water, gas, food, minerals, and other vital molecules for the proper functioning of our cells, tissues, and organs.

There are three major types of blood vessels:
a) Arteries:
The arteries carry oxygen and nutrients from your heart to the tissues of your body.
The veins are taking oxygen-poor blood back to the heart.
Arteries begin with the aorta, the large artery that leaves the heart.
They carry oxygen-rich blood from the heart to all the tissues of the body.
They branch several times as they carry blood away from the heart, becoming smaller and smaller.

b) Capillaries
Capillaries are small, thin blood vessels that connect the arteries to the veins.
Their thin walls allow the passage of oxygen, nutrients, carbon dioxide and waste products to and from tissue cells.

c) Veins
These are blood vessels that return oxygen-poor blood to the heart.
As they get closer to the heart, the veins become larger and larger.
The upper vena cava is a large vein that brings blood from the head and arms to the heart, and the lower vena cava brings blood from the abdomen and legs to the heart.

The pulmonary veins transport oxygenated blood from the lungs to the heart's left atrium. Despite carrying oxygenated blood, this large vessel is still classified as a vein because it transports blood to the heart. The left atrium is entered by four pulmonary veins. The right pulmonary veins are located behind the right atrium and superior vena cava, while the left pulmonary veins are located in front of the descending thoracic aorta.

The pulmonary arteries transport deoxygenated blood from the right ventricle to the alveolar capillaries of the lungs, where it is exchanged for oxygen and carbon dioxide. These are the only arteries that transport deoxygenated blood and are classified as arteries because they transport blood away from the heart.

Vena cava, either of two major trunks, the anterior and posterior venae cavae, that deliver oxygen-depleted blood to the right side of the heart in air-breathing vertebrates, including humans.

Therefore ,the correct Answer is option (A) I only.

Note: Nutrients and oxygen are delivered through a circulatory system to every cell in your body. The heart pumps oxygenated blood through the arteries to your cells. It pumps oxygen-depleted blood away from your cells through your veins.
