muscular and circulatory systems Flashcards
the muscular system is made up of
skeletal muscle, cardiac muscle, and smooth muscle
how the muscular system functions
moves parts of the skeleton, locomotion, and pumps blood
a specific feature about the muscular system
muscle cells contrast and become shorter and thicker
muscle that are attached to bones; they are voluntary muscles, which make our bodies move. they are striped or striated in appearance
skeletal muscles
muscle that is found in the walks of the heart; it contracts involuntary and is also striated
cardiac muscle
muscle that is found in the walls of the digestive tract, blood vessels and other internal organs. The fibers are not striated and they are involuntary
smooth muscle
the circulatory system is made up of
The heart, blood vessels, blood; lymph and lymph structures
consists of two subsystems: the cardiovascular system ( includes the heart which pumps the blood through the blood vessels) and the lymphatic system (which helps yo preserve fluid balance and protects the body against disease
specific features of the circulatory system
the function of the circulatory system
transports materials from one place of the body to another; defends body against disease
somethings the circulatory system does
🔰transports nutrients from the digestive system to all parts of the body
🔰transports oxygen from lungs to all parts of body
🔰transports CO2 and other metabolic wastes from the cells to the excretory organs
🔰helps maintain normal body temp. and fluid balance
🔰protects the body against disease causing organisms. The lymphocytes, which are type of white blood cell, or formed in the lymph tissue: lymph glands. there are two types of lymphocytes: T lymphocytes ( these cells destroy the invader) and B lymphocytes (the anti-body producing cell)
The heart is the key to organ in your circulatory system and pumps your blood and keeps the blood moving throughout your body. It usually beats from 60 to 100 times per minute. but can beat much faster when it needs to. The heart get to messages from the body that tell it when to pump more or less blood depending on a person’s needs. when you’re sleeping, upon stressed enough to provide for the lower amounts of oxygen needed by our bodies at rest. When we are exercising our friend, the heart pumps faster to get more oxygen to our bodies.
how the heart works
The main role of the circulatory system is to transport nutrients, gases such as oxygen and carbon dioxide, hormones, and leased through the body. The circulatory system is divided into three major parts:
🔰heart: last question
🔰blood: made up of liquid called plasma and three types of blood cells: red and white blood cells and platelets
🔰blood vessels: rubbery tubes that carry blood from place to place. Three types of blood vessels are: arteries, veins, and capillaries
the circulatory system
very tiny blood vessels that connect arteries to veins, they exchange food, oxygen and waste between blood and body cells.
capillaries
carry blood to heart
veins
Carry blood away from heart; the main one is the aorta, which carries blood from the heart to the body
arteries
