Question

tell me that capillaries unite together to form the vessels of more diameter called as veins
it is true or flase tell me​

Answer 1

Explanation:

The larger arteries (>10 mm diameter) are generally elastic and the smaller ones (0.1–10 mm) tend to be muscular. Systemic arteries deliver blood to the arterioles, and then to the capillaries, where nutrients and gases are exchanged.

Answer 2

Answer:

False.

Capillaries unite together to form the vessels of more diameter called as Atria.

What is Atria?

• An essential component of the circulatory system is the heart.
• There are four chambers that are separated from one another by heart valves.
• The atria are the names of the upper two heart chambers.
• An interatrial septum divides the atriums into the left and right atriums.
• Ventricles are the names of the heart's lower two chambers.
• The body sends blood back to the heart through the atria, while the heart sends blood out to the body through the ventricles.
• One of the heart's two upper chambers, the atrium, is where blood from the circulatory system enters.
• The atrioventricular valves pump blood from the atria into the heart ventricles.
• The left atrium of the human heart, which receives blood from the pulmonary circulation, and the right atrium, which receives blood from the venae cavae of the systemic circulation, are both present in the heart.
• The atria receive blood during diastole, when they are relaxed, and contract during systole, when they must transfer blood to the ventricles.
• Except for an ear-shaped extension termed an atrial appendage, often known as an auricle, each atrium is essentially cube-shaped. Every creature with a closed circulatory system has an atrium.
