What is a benefit of blood cord over bone marrow for transplant?
These two transplants are similar because they use stem cells as their way to cure a person's malignant disease. The only big difference is stem cells used in cord blood transplant come from a newborn's umbilical cord. This cord is commonly referred to as cord blood and it is similarly effective as the stem cells found in bone marrow.
One cord blood might not be enough to cure an adult. An adult needs two units of cord blood to get cured.
Right so let's break the first task down; what is happening to her circulatory systemfirst of all.
When you exercise, or play football in this case, you are working your muscles and certain places in the body. When this happens, your muscles respire (burn the FOOD to produce ENERGY) more faster than they would normally, so the demand for OXYGEN and GLUCOSE is increased.
Because the muscles are performing cellular RESPIRATION quicker than the norm, they need oxygen and glucose to reach them faster (glucose and oxygen are the components for cellular respiration), and also they need to get rid of their C02 (products of cellular respiration are CARBON DIOXIDE and WATER) so the HEART is now pumping blood around the body at a faster rate in order to provide these cells with what they need. To summarize, the circulatory system has to work harder and faster during exercise to provide the cells at work with glucose and oxygen and to get rid of the waste carbon dioxide.
Right now the next part of the task asks what is happening to her breathing system (aka respiratory system).
This relates to the explanation I gave earlier; the requirement for oxygen is increased so now the respiratory system (in particular the LUNGS) have to work harder and faster to take in more oxygen and to exhale more C02, thus you begin to breathe faster. To summarize, oxygen is inhaled quicker and carbon dioxide is exhaled quicker, therefore the rate of DIFFUSION is increased.
Oh and for the diagrams you could draw a picture of a girl playing football, then next to that have a picture of her lungs and heart (including the arteries/veins) and show how they are working harder during exercise.
Why does newly born baby have 306 bones?
Simply because some bones 'fuse' together after birth. The baby's skull, for example - if it was one piece - would make childbirth much more difficult for the mother. the skull is in pieces so the baby can squeeze through the birth canal, and the pieces fuse together in the first few months of life.
What causes bones in the human body to become brittle?
Your bones can become brittle from lack of calcium. Calcium levels become low when you don't have many dairy or calcium rich products. Coke, Fanta or any other carbonated drinks are VERY bad for calcium levels and can lower them extremely.
What is the common name for cervical vertebrae?

How many bones in shoulder bones?
The human shoulder is a joint consisting of bones, muscles, and ligaments. The two shoulders are located beneath the head connecting the arm and the chest. Each shoulder consists of 2 bones, the clavicle and the scapula, and collectively both shoulders account for 4 bones in the body.
What happens if the epiphyseal cartilage is damaged?
Damaged cartilage can float freely around in the bursa without causing problems. It can also get trapped in the joint, causing the joint to lock up. Arthroscopic surgery is the least invasive way to remove damaged cartilage.
The human body has twelve pairs of ribs for a total of 24 individual ribs.
What is the type of joint in which the head of the femur articulates with the acetabulum?
Ball and socket joint (also known as enarthrosis or spheriodal joint)
Are teeth apart of the skeletal system?

The bones provide support, they work with the muscle to allow movement, they protet organs, store minerals, and produce blood cells.
What bone is located in the centre of your rib cage?
In the posterior position the ribs articulate on individual vertebrae of the spine. I the anterior position they converge on the sternum. There is no bone in the centre of cage made by the ribs.
What does it feel like to fracture your floating ribs?
A normal rib break is usually but not always accompanied by bruising on the chest. The chest wall however has no changes in shape except for swelling or bruising. Pressing on the outside of the chest at the wound site hurts, and so does inhaling deeply. For a standard break like this, there really isn't anything you can do except to treat for pain. It also takes around 2 weeks to a month to heal -- sometimes more.
If your breathing is actually impeded, if you cough up blood, or if there is a depressed area on the chest at the wound site (like a dent), seek medical help instantly.
What is the proper name for a tail bone?
The tail bone in humans is the vestigal coccyx bone, which extends from the end of the pelvic girdle in a straight line with the spine.
How many pairs of ribs in adult human?
there are seven pairs of ribs that are comlpetely attached bonetobone and there are three pairs that are attached wiht cartilage. the last remaining"floating" ribs are not attached. All the ribs are atached to the spine.
What substance in bones gives them a small amount of flexability?
Because they contain collagen, which gives some flexibility
