Cardiovascular+System

Function: To carry, through the blood, gases, nutrients, hormones, and wastes.
 * Cardiovascular System - very thorough, especially characteristics of life! ~Mrs. Rohland **

Organs found in the system: Heart, bone marrow, blood vessels, spleen. (livestrong.com)
 * Body Cavity in which it is found:** The heart is found in the pericardial cavity, the spleen is found in the abdominal cavity. Blood vessels and bone marrow are found throughout the entire body and therefore not in a specific cavity.

Directions: The spleen in inferior to the heart. The heart is medial the spleen. The cappilaries (smallest blood vessel) in the fingers are distal to the heart. The internal jugular is superior and anterior to the heart. The Venous sinuses and the superior opthalmic veins are superior veins.

a. Integumentary System: temperature is controlled by changes in blood flow to the skin. b. Lymphatic System: Returns tissue fluids to the bloodstream. c. Digestive System: Nutrients that are broken down in this system are absorbed into the bloodstream.
 * Example of how the system interacts with other systems:**

Movement: The heart pumps blood through the veins. Responsiveness: The heart must pump fast with increased body movement in order to supply blood and oxygen to needed areas. Growth: The heart, blood vessels, etc. grow from when you are a child to an adult. Reproduction: New cells are formed to repair blood cells and grow new ones. Respiration: Oxygen is passed through the blood stream to other systems. Digestion: Food that is digested is absorbed into the blood stream and passed as nutrients to other systems in need. Absorption: Nutrients, oxygen, blood, hormones all are absorbed into the blood stream and taken to the correct location. Circulation: The blood is pumped through the heart and circulated through the blood vessels through the entire body. Assimilation: Foods original form is altered and therefore has the ability to be absorbed into the blood stream where those are then changed again. Excretion: Wasted is also moved through the blood stream to the appropriate place in which it is disposed of.
 * Characteristics of life**

Metabolism fits in with the Cardiovascular system because food and nutrients are broken down, digested, and aborbed into the blood stream, and are then assimilated. These substances are then circulated throughout our entire body by means of the cardiovascular system (the blood vessels).

Homeostasis fits in with the organ system of the cardiovascular system because if the heart did not pump correctly, blood supply would not be adequate and therefore the nutrients, oxygen, etc would not reach places in needed to in the correct amount of time and therefore homeostasis would be off balance. In return, if the organism wasn't receiving enough nutrients, or oxygen, the blood stream could not supply the rest of the body with what it needs and again the balance would be off.
