Yes
the function of a muscle cell is, by definition, to move. this can be accomplished when the cell contracts. contracting makes it denser, which is why when you feel a relaxed muscle in your arm suddenly tense up, it hardens.A muscle cell expands and contracts in order to allow the human body to control the movement of it's limbs.
Respiratory rate. Breath rate, or respiration rate.
tidal volume
Static stretching Guidelines: - Hold each static stretch for 10-30 seconds each and repeat on each side 3 to 4 times - Total stretching time generally around 10 minutes minimum on each exercise day - Do not bounce or jerk back and forth - Warm up for 5-10 minutes before stretching when the muscles are at their warmest or stretch after aerobic exercise - never stretch cold muscles - Move slowly into a static stretch position - Stretch to a point of gentle tension, but not pain. - Inhale before start of stretch, exhale during stretch, and breathe evenly while holding the stretch at its end position Stop immediately if you feel pain that is more than a mere discomfort
The only Biological tissue that is able to contract is MUSCLE tissue and this is because of the specialized proteins: actin and myosin that slide across each other.
The answer is false. I just finished my test with the same question, so that's how I know its false.
all of them, muscles can only contract and relax
Primiary respiratory drive in a healthy person is based on carbon dioxide levels. In a healthy person each time the carbon dioxide level gets high the brain stem send nerve impulses down the spinal cord that cause the diaphragm and the intercostal muscles to contract.
Not exactly. Your intercostal muscles are the muscles that contract and they're found inbetween in each rib in the rib cage. When this contracts, as well as the diapragm, the lungs will have less air pressure inside them, making you breathe in. Hope this helped? :)
CO2 (Carbon Dioxide) leaves the body with each exhale breath.
The anatomical features of the respiratory system include airways (nose,pharynx,larynx, trachea, bronchus), lungs, and the respiratory muscles (sternocleidomastoid, platysma, scalene muscle of the neck, external intercostal muscle and diaphragm)
