Flashcards in Circulatory and Respiratory Systems (8.11) – Part 1 and Part 2 Deck (39):
Responsible for connecting all the cells of the whole organism. It distributes nutrients, oxygen, hormones, and functions in waste retrieval.
Evolution of the Circulatory system:
It started with a _________ Cavity. (As seen in Cnidarians and Platyhelminthes.)
Blood bathes the organs by moving through sinuses (spaces).
The system has a tubular heart with directional arteries to distribute blood.
Seen in Arthropods and some Mollusks.
Open Circulatory System
Blood is confined to traveling through blood vessels under pressure.
A muscular chambered heart mostly (Not in annelids.)(2,3,4 chambers)
Found in Annelids, some mollusks, vertebrates
Closed Circulatory System
These chambers receive blood coming into the heart.
They are composed of a thin layer muscle tissue.
These chambers pump blood away from the heart.
They are composed of a thick layer of muscle tissue.
Mammals, birds, reptiles, and amphibians have a ______ _____ system.
One loop for getting oxygen; one loop for delivering oxygen.
_____ vascular system (Echinodermata) (Madreporite, Tube feet, canals are the parts.)
These are large blood vessels carrying blood away from the heart.
These are medium sized vessels carrying blood away from the heart.
These are the smallest blood vessels where nutrients and oxygen diffuse out.
These are small blood vessels that collect waste materials from the tissues.
These are large blood vessels that carry blood toward the heart.
The blood mainly is in the digestive organs.
During Digestion of Food
The blood is mostly in the muscles and skin; not the digestive organs.
These are red blood cells-RBC’s (“erythro” means “red”; “cyte” means “cell”)
______ uses iron (Fe) to hold oxygen. (“heme” means “iron”)
Each RBC can hold 1 billion oxygen molecules.
These are white blood cells – WBC’s (“leuko” means “white”)
They protect our bodies against invading organisms or materials.
These are pieces of RBC’s used for making clots.
These are for gas exchange with the environment.
(Oxygen in and Carbon dioxide out.)
Oxygen is need for cellular respiration; Carbon dioxide is the waste product of cellular respiration.
This term refers to where the oxygen molecules are located. It is either water or air.
This term refers to where the gas exchange occurs.
Diffusion must occur across a ______ surface. Gases do not diffuse across dry surfaces.
A large surface area is needed to get large amounts of gas exchange to occur. ______ in the surface increases surface area within a small space.
Gills, Lungs, Tracheal tubes, Skin, membranes are all ________ surfaces.
Works with the circulatory system ( That is why they are always located together.)
Mammalian Respiratory system is located in the ________ Cavity (Chest)
These cavities warm, moisten, and clean the air using mucous and hairs.
Nostrils and Naval Cavity
This is the back of mouth
This is the top of trachea
This muscular flap covers the trachea by bending over the opening.
These vibrate to make sounds. (You can only talk while
exhaling because the moving air is causing the vibration by “catching” the wind, much like a parachute catches air.)
True and False Vocal Cords
A.K.A. windpipe) It is protected by C- shaped cartilage rods on the front side.
(There is one for each lung.) Cartilage keeps them open for air to travel through.
These carry air into each lobe of each lung.
This is an inflammation of the air ways.
This condition is having trouble breathing due to airways swelling shut.
