Circulatory System

Functionally both the respiratory and digestive system are tasked with the extraction of the requirements of metabolism (energy in the form of food, oxygen from the air). On a more superficial level there are certain morphological similarities. Both the digestive system and the lungs have invaginations or folding of the epithelial surfaces in order to maximize surface area.

The tiniest blood vessels that carry oxygen-rich blood are the capillaries. These capillaries form a bed. The arterioles that carry the blood into the bed are high in oxygen. The oxygen is released to the cells. The rest of the bed is low in oxygen and venules carry deoxygenated blood to the veins back to the heart.

The undigested waste products does not enter your body cavity. That is called as faecal matter. Scientifically speaking the food you eat is not "Inside" your body cavity. It is always "Outside" the body cavity. You go for extracellular type of digestion. I found it very difficult to teach the same in my dental college class.

Pulmonary circulation through the blood vessels and capillaries.

The main component is the Heart which pumps the blood throughout the body. This blood is carried to various parts of the body by Arteries and Veins.

Capillaries are known as exchange vessels. Capillaries are the smallest of vessels and allow nutrients and waste to pass through blood and body.

1. What is the anatomy of the cardiovascular system?

2. What are the causes of coronary artery disease?

3. Is cigarette smoking a really big risk factor for heart disease?

they increase in size as we get older, so we can never tell.

The lacrimal puncta/canaliculi/sac & hasolacrimal duct in the eye & accessory structures secrete and contain lysozyme which is an antibacterial enzyme(naturally occurring in tears). due to its acidity its responsible for killing some bacteria.

The circulatory system is the system running through out the body, carrying nutrients and oxygen to all cells of the body. It consists of the heart and the blood vessels. The exchange and transfer of material takes through the blood. The arteries carry blood away from the heart and the veins carry it back to the heart.

Blood flows

Each beat of the heart pushes blood to the brain. It takes about a minute, or 70 beats to move it throughout your body.

The circulatory system and respiratory system work together to provide the body's cells with oxygen and to carry away the carbon dioxide that cells generate as respiratory waste. The respiratory system gets air into lungs and in the small air sacs were oxygen is transported into the blood, and the circulatory system carries the oxygen in the red blood cells and delivers it to cells in need of oxygen. The oxygen is stored in the hemoglobin in the blood, and the blood is pumped around the bodily organs by the heart, releasing oxygen at the organs.

Cells get a lot of energy from food. But the food you eat is not needed by cells.

Gasses are exchanged (CO2 is lost & O2 is gained).

A neuron is a fundamental cell of the nervous tissue which receives and maufactures information and generates and transmits responses and cells are composed of several different compounds (water, carbohydrates, proteins etc.) which combine to forma cell. In conclusion, a neuron basically belongs to the nervous tissue while ordinary cells generally belong to the blood tissue.

The lymph nodes are all over the body and each area or region is drained by its group of lymph nodes. They do not pass through one node but they drain in the thoracic duct which ultimately opens and drains in the large veins of the neck on the left side

There will be higher pressure in the left atrium, when there is mitral stenosis. There will dilatation of the left atrium as well as there will hypertrophy of the left atrium. There will raise in the pulmonary veins. This will lead to pulmonary edema. This will eventually lead to high pressure in pulmonary arteries. That is called as pulmonary hypertension. The pressure in right ventricle will increase. Then the pressure in the right atrium will increase. Then the pressure in the systemic venous side will increase. This will lead to right sided heart failure.

As the blood moves through the aorta, the friction of the walls of the aorta decreases velocity. This velocity decrease results in a decrease in pressure.

Your circulatory system is so important! It consists of your blood, blood vessels, and heart. Your heart brings blood to your heart through your veins, and when it gets to your heart, it goes through your right atrium, through your right ventricle, into your lungs through your arteries, back into your heart through veins, into your left atrium, through your left ventricle, and goes through your biggest artery, the aorta, and then other arteries to go to every cell in your body. You have 3 types of blood vessels; veins, capillaries, and arteries. Veins take blood toward the heart, arteries take blood away from the heart, and capillaries let blood kind of travel wherever, and collects oxygen from the air sacs, which are covered in capillaries. The digestive, respiratory, and urinary systems all connect with the circulatory system, mostly by having blood carry things such as oxygen and carbon dioxide throughout the body Hope this helps!

Blood is actually the color red, so blood is represented by the color red because it is red. It is sometimes represented by blue to represent deoxygenated blood, which is actually dark red as opposed to the bright red of oxgyenated blood. This is purely for visual purposes so those learning about the circulatory system can see clearly where there is oxygenated blood and where there is deoxygenated blood. The myth that human blood is blue is not true, but the blood of a horseshoe crab is actually the color blue.

Ch2o + o + o2 -> co2 + h2o + atp

The blood moves in a lateral direction to the distal right thumb. Then the blood comes back in a proximal direction toward the medial body, where the heart is located.
