system where afferent neurons synapse with interneurons which in turn synapse with efferent or motor neurons. This motor neuron then relays the information out of the brain to an effector. In this case‚ the effector is a skeletal muscle that causes the reflex response to occur. Reaction time is a measure of the time between when the stimulus is delivered and the response occurs. This speed can vary person-to-person depending on the speed of transmission of the signal from neuron to neuron‚ as well as the

more frequent. Briefly describe the reflex that regulates normal respiratory rate and depth. Which gas contributes most to the reflex? Refer to your text for further information. The regulation of normal respiratory rate and depth is due to respiratory centers in the medulla oblongata (ventral respiratory group and dorsal respiratory group)‚ and chemoreceptors (central and peripheral). CO2 is the gas that contributes most to the breathing reflex. C. Measurement of Lung Volumes and

I was walking down the trail to Sombrio Beach which is about a 1.5k hike down a steep trail to the ocean. I had a surfboard under my right arm‚ an axe in my left hand‚ and a large 40 litre hiking backpack fully loaded with supplies on my back. About half way down there is a left turn in the trail which has a declining

02.02 Prenatal Development and the Newborn Prenatal Development Prenatal development describes the period of time from a baby’s conception to the day parents welcome him or her into the world. This time period is full of remarkable changes that have a dramatic impact on an individual’s development later in life. Learning about the earliest developmental processes allows us to better understand the foundation upon which development throughout the lifespan is built. Prenatal development occurs in

for bacteria. B) What is the Cough Reflex? Describe the process that Cari’s respiratory system is using to clear her lungs by coughing? a. The cough reflex is used to get things like irritants and fluid which causes us to have sputum out of the nasal passage and pharynx. The cilia or little hairs that are in our trachea is trying to move that mucus and crap from her lungs because they don’t want it there so when there is too much mucus it triggers the cough reflex try to get it out to make more room

The cough reflex is used to clear sputum and irritants that are in the nasal passages and pharynx. There are cilia in her trachea that is moving mucus up from the lungs. When the mucus becomes abundant‚ it triggers the cough reflex. C.) Which structures found in the bronchioles and alveoli normally would protect
