What happens to the muscles of the ventricle wall when the pressure in the ventricle is increasing?
Blood flows to the heart when the ventricle contracts

Trabeculae carne
Are the papillary muscles and chordae tendineae in the right ventricle also present in the left ventricle?
yes
What chamber of the heart do you think is the strongest?
Left ventricle has the strongest muscles. This ventricle has to pump blood to entire body parts. The blood pressure in the systemic aorta is about 120/80 mm of mercury. This has to be maintained by this chamber. The right ventricle has to pump blood to the lungs only. The systolic blood pressure here is about 25 mm of mercury, much less as compared to systemic blood pressure. When you actually see the muscles of the heart of cadaver, you get the idea very clearly and without further questioning.
Where are the papillary muscles found?
inside the left and right ventricle
What do Vasodilator drugs do to you?
Vasodilator drugs work directly on the muscles of one's arteries, dilating them and increasing blood flow. This eases pressure on the heart and lowers blood pressure.
Why does the left ventricle have a thick muscular wall?
The left ventricle pumps the most blood out of the four, the blood from the left ventricle travels all over the body. The left ventricle pumps the most blood out of the four, the blood from the left ventricle travels all over the body.
How many papillary muscles are located in the right ventricle?
The right ventricle of the heart typically contains three papillary muscles: anterior, posterior, and septal. These muscles attach to the tricuspid valve leaflets via chordae tendineae to help prevent valve regurgitation.
What happens to the chest during inhalation?
During inhalation, the diaphragm contracts and moves downward, increasing the volume inside the chest cavity. This increase in volume causes a decrease in pressure, leading to air rushing into the lungs to equalize the pressure. As a result, the chest expands to accommodate the incoming air.
What pumps blood into the heart?
The right ventricle pumps blood into the pulmonary artery.
What happens if you flex your muscles during a blood pressure test?
It'll Increase your blood pressure because the blood is being rushed to the area where your flexing, which causes your blood pressure to rise.
What happens when relaxation of the diaphragm and intercostal muscles increases intrapulmonic and intrathoracic pressure?
Exhalation describes the state when the diaphragm relaxes and intrapulmonic and intrathoracic pressure increases.
What is the breathing process?
Breathing consists of two phases, inspiration and expiration.During inspiration, the diaphragm and the intercostal muscles contract. The diaphragm moves downwards increasing the volume of the thoracic (chest) cavity, and the intercostal muscles pull the ribs up expanding the rib cage and further increasing this volume. This increase of volume lowers the air pressure in the alveoli to below atmospheric pressure. Because air always flows from a region of high pressure to a region of lower pressure, it rushes in through the respiratory tract and into the alveoli. This is called negative pressure breathing, changing the pressure inside the lungs relative to the pressure of the outside atmosphere.In contrast to inspiration, during expiration the diaphragm and intercostal muscles relax. This returns the thoracic cavity to it's original volume, increasing the air pressure in the lungs, and forcing the air out.
