A developing embryo has a complete endocardial cushion defect. The foetus develops to full-term and is born at 39 weeks gestation. 1) Describe which septum are missing in this newborn (2 marks); 2) Compare and contrast the blood flow in the developing foetus (1 mark), to that in the newborn, including oxygenation and shunting of blood (1 mark);

3) Describe which side of the heart will have increased blood volume, and how this increased blood volume will impact the heart wall thickness over time (1 mark). Hint: Think about which side of the heart will end up with more blood (i.e. blood volume) as the heart beats, and identify how this increased blood volume will impact the heart tissue growth (i.e. hypertrophy etc.) Key words: Atria, Ventricle, shunt, hypertrophy Use dot points to answer this question *Use dot points

1) Describe which septum are missing in this newborn (2 marks); Interatrial septum 2) Compare and contrast the blood flow in the developing foetus (1 mark), to that in the newborn, including oxygenation and shunting o blood (1 mark); 3) Describe which side of the heart will have increased blood volume, and how this increased blood volume will impact the heart wall thickness over time (1 mark).

A cell is at equilibrium in an aqueous solution of$$300\mathrm{ml}$$osmoles of sodium chloride. Upon its placement in a Calcium chloride solution of$$300\mathrm{ml}$$osmoles, what will be the net movement of fluid? – No change

Consider two aqueous solutions of different concentration separated by a semipermeable membrane. In this situation, osmosis results in: A. water molecules moving to the side where the solution concentration is lower. B. the more concentrated solution becoming even more concentrated. C. the more dilute solution becoming even more dilute. D. the more concentrated solution becomes more dilute.

Could you please type the answers to see clear .) thank you ! (Human PHYSIOLOGY) Which of these statements are correct and which are incorrect Cotransport always involves Na+ and a non -ionized solute (such as glucose).

2- Cotransporters can move their transported solutes in either direction across a cell membrane.

3- Cotransport consumes metabolic energy directly.

4- Counter-transport always requires Na+ participation.

5- Facilitated diffusion and primary and secondary active transport are all examples of carrier -mediated transport.

6- The energy for secondary active transport comes indirectly from the activity of the Na+, K+ ATPase.

48- Place each of these into its appropriate category.

Facilitated diffusion, Primary active transport , Secondary active transport

1- Coupled transport of glucose and Na+ into cells.

2- Coupled transport of Na+ into cells and K+ out of cells.

3- Movement of glucose from the interstitial fluid into cells.

Why is the use of proper body mechanics important for the healthcare worker and the patient? (be specific). Identify each component of the chain of infection and give 1 method for each component that a healthcare professional can use to interrupt the cycle of infection.
