In order to achieve the objectives of an organisation, the HRM section or department must carry out a number of functions. The key functions of HRM can be summarized as the acquisition, maintenance, development and termination of employees.
Acquisition: This is the 'getting' phase of HRM. It includes estimating both the future demand and supply for human resources and integrating these resources into a total human resource strategy. In other words, the objectives and future directions of the organisation must be known before any reliable forecasts of people needs can be made. The acquiring process includes recruiting, selection and the socialization or induction of new employees.
Maintenance This is the 'keeping' function and involves providing benefits, services and working conditions that are needed if individuals are to remain committed to the workplace.
The atria are the upper chambers of the heart that receive blood returning from the body (right atrium) and the lungs (left atrium). They contract to push blood into the ventricles for efficient circulation.
What is transpiration in humans?
Transpiration is the movement of water through a plant and loss or evaporation of that water from leaves, stems and flowers. In a human, the loss of water through the skin as perspiration and evaporation is called transepidermal diffusion. In both cases the point of evaporation is to cool the plant or human.
Is there another name for a ball check valve?
No
Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave. There are various types of check valves used in a wide variety of application. And a ball check valve is one of types of check valves, it a check valve in which the closing member, the movable part to block the flow, is a spherical ball.
Then a ball valve is a valve with a spherical disc, the part of the valve which controls the flow through it. The sphere has a hole, or port, through the middle so that when the port is in line with both ends of the valve, flow will occur.
As you see, they are not the same.

What is it?
A heart attack is basically a clot (embolism) that gets stuck in one of the hearts blood vessels. Heart attacks differ in seriousness depending on where the blockage is. Having a blockage in one of the main vessels can kill in 3 minutes. However, blockages in smaller vessels can go un-noticed for days.
Symptoms:
Central crushing chest pain that could spread to shoulders or face
Fast Pulse and breathing
Collapse
Fear
What will happen?
The sooner a person calls an ambulance, the better the patients chance of survival. In the UK, Paramedics can give powerful thrombolytic drugs such as tenecteplase which break down the clot in the heart. Also, Paramedics / Ambulance technicians will perform a 12 Lead ECG. This is a tracing of the patients heart electrical (myocardial) activity. From the results of this, they can interpret exactly where in the heart the blockage is.
When the patient gets to hospital. The doctors may finish the thrombolysis (giving the patient thrombolytic drugs). Or they may perform stenting surgery, where a balloon is put into the vessel of the heart and used to open it up again.
How does the human heart look like?
In reality, the human heart does not look like the traditional heart depicted on Valentines Day cards. The human heart has several cavities; both ventricles and atrium's. It also contains valves (pulmonary, aortic, mitral, tricuspid), which move the blood throughout (in and out of) the heart. The human heart is about the size of a human fist and, because the heart is a muscle with lots of blood supplied to it, it appears red like meat.
Hope this helps!
When you sneeze all bodily functions stop even your heart?
In a word, no, your heart does not stop when you sneeze. From my
perspective, it is hard to even imagine what this would mean. A sneeze
itself is really a very brief event, occurring in a shorter time then a
heartbeat. Of course, there is the building up to the sneeze (the "ah" of
the "ah-choo"), but the heart certainly does not stop beating because of
this ah-ing. Check your pulse next time to prove this to yourself.

Can a heart be slightly twisted or in the wrong position like outside the rib cage?
I believe the heart can be compressed without outright failure, but anything that impedes the heart's motion is extremely dangerous. The heart cannot be outside the rib cage unless the rib cage were to be suddenly torn away in some sort of accident.
Liasdaughter agrees and adds:
The heart also can be on the right side instead of the more usual left. But, those persons are born that way.
Heart position can vary enourmasely from the very slight tilting( causing axis deviation) to dextracardia, where the heart is on the other side of the chest. All can be normal for the person.
Ayraayra: I would also like to add that left sided heart failure can cause hypertrophy which means the size increases which can then slightly displace your heart more towards the left side.
