what structure receives lymph from lymph vessels and drains into the venous system in the chest area at the junction of the subclavian and internal jugular veins?
What structure do insects use to deliver air close to each body cell?- saclike lungs - pharynx - elaborate branching air tubes called tracheae - spiracles
which lymph nodes are found bilaterally in the occiptial region and receives lymph from this area of the scalp?
lymph nodes are ______-shaped structures grouped in clusters along the connecting lymphatic vessels
what is the tissue fluid that drains from a surrounding region into the lymphatic system?
what filters out toxic products from the lymph to prevent their entry into the blood system?
true/false, lymphatic vessels have valves to prevent backflow of disease
whaat are part of the immune system and help fight diseases?
true/false, the tonsillar tissue of the oral cavity is part of the immune system
lymph from a particular area drains into which classification of nodes?
During inhalation,- the diaphragm relaxes. - the volume of the thoracic cavity decreases. - air moves up the trachea. - the diaphragm and rib muscles contract. - oxygen molecules move into the lungs, and carbon dioxide molecules move out of the lungs.
The lungs of reptiles are better developed than those of amphibians because reptiles:- lay shelled eggs. - have a dry, scaly skin. - are larger animals. - use oxygen for cellular processes. - have a higher metabolic rate.
Movement of O2 from the outside air to respiratory surfaces by breathing is an example of:- diffusion. - active transport. - facilitated diffusion. - bulk flow. - osmosis.
After blood becomes oxygenated,- it returns to the heart, and is then pumped to the lungs. - it does not return to the heart, but goes directly to the lungs. - it returns to the heart, and is then pumped to body cells. - it does not return to the heart, but goes directly to capillaries that supply the body's cells with oxygen. - it does not return to the heart, but goes to the nose and mouth.
Which respiratory system characteristics are shared by fish, frogs, jellyfish, and earthworms?- respiratory system with a complex network of tubes - lack of a true circulatory system - internal respiratory structures - gas exchange across a moist respiratory surface - gas exchange across the skin
All of the following are respiratory surfaces EXCEPT:- alveoli of a raccoon. - skin of an earthworm. - gills of a fish. - tracheae of a fly. - bat wings.
Hemoglobin- uses ATP to move oxygen from blood to body cells. - is the site of cellular respiration. - is a protein that can bind four molecules of oxygen. - is found in blood plasma. - has five subunits.
what are mainly parallel with the venous blood vessels but are more numerous?
what consists of a network of lymphatic vessels linking lymph nodes throughout most of the body?
Where do air from the nose and air from the mouth join?- larynx - pharynx - bronchioles - bronchi - trachea
