preventing blood loss during injury
O regulating blood flow through the brain
O keeping brain blood separate from body blood
O keeping foreign particles out of the brain
Answer:
The correct answer is - keeping foreign particles out of the brain
Explanation:
The blood-brain barrier or BBB is the barrier of endothelial cells that is highly selective and semipermeable in nature that allows selective molecules like certain lipids, gas, and water and prevent other solutes and pathogens, toxins, and infectious agents from circulating blood between capillaries and brain.

Q1 What are the different chambers of the heart acoording to the flow of
blood from the vena cava?
Answer:
Taking into account the flow of blood coming from the vena cava, the chambers of the heart through which it flows are the right auricle, right ventricle, left auricle and left ventricle.
Explanation:
In the human being the heart is divided in four chambers, which handle volume and pressure to be able to irrigate the different areas of the body.
The blood that comes from the vena cava is not oxygenated, so it must reach the lungs to receive oxygen and then distribute this gas throughout the body. The heart is the pump that allows the function of transporting blood, and its four chambers are responsible for allowing it.
If we take into account the venous blood that arrives through the vena cava, the route of the blood through each chamber is
Right auricle, receives the blood from the general venous circulation, and propels it to the adjacent ventricle.Right ventricle, from where the blood goes to the lungs through the pulmonary arteries.Left auricle, which receives the oxygenated blood through the pulmonary veins.Left ventricle, which receives the blood from the left atrium and propels it to the entire body, through the aortic artery and its branches.The distribution of the heart in chambers allows it to manage an efficient circulatory system, divided into two circuits: the major circulation and minor circulation.

How does having skill-related fitness help you perform successfully in your everyday activities, at school and at home?
Describe one exercise you did that helps improve your striking and your reaction time skills (at least one of your exercises must qualify).
Describe how balance and/or coordination is needed for at least three things that you do every day.
Name an activity or sport. What activity or game could a player practice during the off season to improve his/her performance? What similar movement skills are used when practicing this offseason activity?
Try the aquatics exercises you learned in lesson 02.07 Aquatics. What was the most difficult part of completing the leg action of treading water or bicycling in the air? Why?
Describe an outdoor pursuit you currently participate in, or an outdoor pursuit you would like to pursue in the future, including equipment needed and safety procedures.
Did you meet your goal throughout this activity log? Why or why not?
Answer: 1: If this is something that you like, then it gives you a reason to strive more at school so you can keep doing it.
(Take these with a grain of salt as I don't know exactly what your doing)
2: Mixed Martial arts. This gave me self confidence and more Confidence
3 This prevents ankle injuries, keeps you up on your feet and the ability to know where you are in space
4 I can improve in basketball if i'm also a soccer player. This can give me more hustle and endurance/stamina for the next game.
5 (don't know what lesson 2.07 is)
6 Hiking. I don't do this like on a professional level but you need running shoes and the clothes needed for the weather hiking with. The one and only procedure i'd say is no running.

Hey there! Thank you for posting this answer. Sorry, I'm late, but here's my answer! :D
Answer:
1.) It makes me more knowledgeable about activities and safe ways to perform them. Like, for example, doing every activity without getting hurt.
2.) Karate probably.
3.) Plain old walking. I am constantly falling forward, and you have to keep my balance and coordinate the movement of my feet with the forward motion of my body.
4.) I play soccer. So that would mean that I can play hockey in the off-season because of the similar movements and fast-paced play.
5.) My guess is the leg action of treading water. The leg action of treading water requires more time and hard work than air, so it is a more difficult aquatic exercise.
6.) I didn't get this on my FLVS assignment, sorry :(
7.) Yes, because all of the activities I do in more than an hour.

None.

What does the formula ´220´ -your age tell you?
Answer:
The formula "220 - age" is the estimate of the maximum heart rate.
Explanation:
The heart rate is determined by the number of heartbeats per minute, which is a relatively easy parameter to measure.
In an adult, the heart rate is in the range of 60 and 100 beats per minute, under normal conditions. The maximum heart rate (MHR) is the value of beats per minute that should not be exceeded during the practice of physical activity, in order not to produce damage to the heart or cardiovascular system. The formula is:
MHR = 220 - age
The use of MHR has been very controversial, mainly because the formula provides an estimated value, but there is not enough scientific data available.
Currently, it is often used to estimate and dose the physical activity that a person can perform safely.
